Abstract

The invention discloses a method and a system for automatically arranging and inlaying nails on a tire tread pattern, which comprises the following steps of: constructing a pitch position matrix A, converting the pitch position matrix A into a two-dimensional pitch inlaying nail distribution matrix B, reading a drawing by using an API (Application Program Interface) provided by drawing software to generate a pitch color matrix C, and carrying out automatic arrangement and inlaying on the two-dimensional pitch inlaying nail distribution matrix B; and then corresponding elements in the pitch color matrix C are adjusted according to the pitch nailing distribution matrix B. And based on the multi-color coding matrix, elements in the pitch nailing distribution matrix B and elements in the pitch color matrix C are automatically matched according to color and length attributes by circulating elements in a pitch position matrix A set, the position where nails are to be nailed is found, and nails of a specified type are placed. According to the method, the design efficiency is remarkably improved, the time and errors of manual operation are reduced, the design process is accelerated, meanwhile, the working process is optimized, and the design quality is improved.
